While I Live (1947)

In 1922, young composer and pianist Olwen Trevelyan, troubled and sleepless over her inability to finish the final notes of her composition, falls to her death from the cliffs of Cornwall. As years pass, Olwen's sister Julia obsessively keeps Olwen's memory alive in the family home. The young composer gains posthumous fame because of her tragic death and her haunting, unfinished composition, "The Dream of Olwen." Twenty-five years later, on the anniversary of Olwen's death, the family gathers to listen to a radio broadcast of "The Dream." Suddenly, a young woman bursts into the room, sits down at the piano, and begins playing along with the music. Claiming to have lost her memory, the young woman is cared for by the obsessed Julia, who comes to believe she is the reincarnation of her dead sister.
